Generate invoice, but don't auto renew domain on payment?

[xyzulu]

I have a few domains I have transferred to a new registrar and already renewed them in the process. I want WHMCS to still generate the domain renewal invoice as per normal, but when the customer pays NOT to renew their domain this time.

 

Any pointers?

 

PS I know how to stop an already generated invoice from renewing the domain name, but in this case the invoices are yet to be generated.

 

Thanks in advance.
